BOBBIN=HOLDER.

SFEGIFECATON forming part of Letters Patent No. 678,587, dated July 16, 1901. Application filed April 18, 1901. Serial No. 56,436. (No model.)

To ctZ whom it may concern.'

Be it known that I, JOHN RONEY, a citizen of the United States, residing at Voonsoeket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Bobbin-Holders, of which the following is a specieation.

My invention relates to that type of bobbin-holders which comprise holding-jaws and ro an annular coiled spring encircling said jaws; and it has for one of its objects to provide such a bobbin-holder inwhich the connections between the holding-jaws and the body or main portion of the holder are inclosed, i5 this in order to prevent dirt and lint from collecting on such connections and interferfering with the free action of the jaws when the head of a bobbin is pressed down between the same and also to preclude frictional zo wear of those portions of the jaws which are connected to the body against the part on which the holder turns, and thereby prevent the jaws becoming loose and incapable of tightly grasping and holding the bobbin-head.

Another object of the invention is to provide a bobbin-holder of the type defined, in which the holding-jaws are equipped with means for retaining the encircling spring about them and preventing said spring bego ing drawn off when the bobbin is doffed because of the yarn being entangled in the spring, which frequently happens.

Other advantageous features of the invention will be fully understood from the following description and claims when taken in conjunction with the accompanying drawings, in which- Figure lisaplan viewof my improved bobbin-holder. Fig. 2 is an elevation of the same 4o with a portion in diametrical section. Fig.

3 is a horizontal section taken on the broken line 3 3 of Fig. 2, and Fig. 4 comprises disconnected sectional views oi' the disk and casing-sections forming part of the body or main portion ofthe holder.

Similar letters of reference designate corresponding parts in all of the views of the drawings.

In the preferred embodiment of my invention the body or main portion of the holder is made up of a bushing A, of brass, and an annular disk B and casing-sections O D, of suitable sheet metal, as steel. The bushing is provided with a reduced portion a, as best shown in Fig. 2, and on this reduced portion are arranged the disk and the casing-sections, the former being interposed between the latter, which have flanges b at their inner edges, and said disk and casing-sections being tightly secured in position by a flange 6o c at the upper end of the bushing. The disk B is provided, as best shown in Fig. 3, with three, more or less, slots c', while the casingsections O D, which are larger in diameter than the disk, are provided with marginal flanges CZ e, respectively, the flange e of the section D surrounding the flange d of the section O, as shown in Fig. 2. In their said anges d e the casing-sections have registered openings f for a purpose presently pointed 7o out.

E E are the holdingjaws, of which 'three are employed. These jaws are designed to grasp the head of a bobbin and are disposed, as shown, with reference to the body or main portionof the holder. At their lower edges they are provided with inwardlydirected approximately horizontal arms F, which extend through the openingsfinto the casing formed by the sections C D and terminate at their 8o inner ends in curved hooks or lugs g, arranged in the apertures c of the disk B. The hooks or lugs g of the arms F fit loosely in the apertures or slots of the disk B, as best shown in Fig. 2, and consequently it will be observed that the jaws E are free to oscillate or swing vertically. Said jaws, however, are securely held against casual lateral play by reason of the fact that the Width of the arms F corresponds to the length of the slots c' in the disk 9o B and the length of the registered apertures f in the lapped iianges of the casing-sections.

G is an annular coiled spring which girdles or encircles the jaws E and has for its purpose to press said jaws inwardly against the head of the bobbin to be held, and H H are strips or tongues which depend from the upper edges of the jaws and rest over the spring after the manner best shown in Fig. 2. These strips are bent down over the spring after the ioo latter is placed in its proper position about the jaws, and they serve to effectually prevent the spring being drawn off the jaws in the event of the yarn being entangled with the spring when the bobbin is doffed.

It will be appreciated from the foregoing that while very silnple and inexpensive in construction my improved bobbin-holder is practically dust-proof-that is to say, the connections between the holding-jaws and the body are inclosed and the liability of dust and lint collecting on said connections and interfering with the free working of the jaws is reduced to a minimum. It will also be appreciated that by virtue of the hooks or lugs of the jaws which engage the slots in the disk B being inclosed they are protected against frictional wear on the part on which the holder rotates, and consequently there is no liability of the jaws becoming loose and permitting the bobbin to fly out of the holder.

I have entered into a detail description of the construction and relative arrangement of the parts embraced in/the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. A bobbin-holder comprising a hollow body closed at its top and bottom, and having openings in its side, and spring-pressed holding-jaws having portions extending into the body through the openings in the side thereof, and loosely connected to said body inside the same.

2. A bobbin-holder comprising a hollow body closed at its top and bottom and having openings in its side, and also having an interior disk, holding-jaws having portions extending into the body through the openings in the side thereof and loosely connected to the interior disk, and an annular coiled spring encircling the holding-jaws.

3. A bobbin-holder, comprising a body or main portion,holdingjaws connected thereto, an annular coiled spring encircling the jaws, and guards on the jaws resting over the spring and adapted to prevent casual removal thereof.

4. A bobbin-holder comprising a body or main portion, holding-jaws connected thereto and having guard strips or tongues depending from their upper edges, and an annular coiled spring encircling the jaws and arranged within the guard strips or tongues thereof.

5. Inabobbin-holder,tl1e combination with the body comprising a bushing, and the annular, apertured disk and the annular casingsections surrounding and secured on the bushing; said casing-sections having lapped flanges and registered apertures therein; of the holding-jaws having inwardly-directed arms extending through the apertures of the lapped flanges of the casing-sections and termeans for securing said casing-sections and disk on the reduced portion of the bushing; of the holding-jaws having inwardly-directed arms extending through the openings in the lapped flanges of the casing-sections and terminating at their inner ends in hooks or lugs arranged in the apertures or slots of the disk, and means for pressing said jaws inwardly.

7. In a bobbinholder,the combination with the body comprising a bushing having a reduced portion, the annular casing-sections having flanges at their inner edges surrounding the reduced portion of the bushing and also having lapped flanges at their outer edges and openings therein, the annular disk surrounding the reduced portion of the bushing between the inner flanges of the casingsections, and having apertures or slots, and means for securing said casing-sections and disk on the reduced portion of the bushing; of the holdingjaws having the depending strips or tongues, and also having inwardlydirected arms extending through the openings in the lapped flanges of the casing-sections and terminating at their inner ends in hooks or lugs arranged in the apertures or slots of the disk, and an annular coiled spring encircling the jaws and arranged within the strips or tongues thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN RONEY.
